Rockwool Home Energy Audit in Seguin: What to Know First
We provide independent Rockwool home energy audit in Seguin, typically scheduled within 48 hours and completed in a single visit. Most audits run between $280 and $520 depending on home size and which diagnostics are needed; we put the written price in your hand before any work starts. This page is for homeowners who’ve installed Rockwool Comfortbatt, Comfortboard, or AFB evo in their walls or attic and need to know whether the insulation is performing as designed, or whether air leaks are bypassing it entirely. Call (830) 549-6646 to book a slot or get a free second opinion on another contractor’s estimate.
How Rockwool Products Fail - and How We Fix Them
- Comfortbatt R-23 compressed in 2×6 walls. Rockwool’s rigid batts don’t spring back like fiberglass after improper installation or plumbing/electrical compression. We find this in Seguin’s 1990s-era subdivisions near Kingsbury Street, where retrofits were done without air-sealing first. We remove the compressed batt, seal the top plates and electrical penetrations with acoustic sealant, then reinstall to full loft.
- Comfortboard 80 on exterior walls taking bulk water. The semi-rigid boards are hydrophobic, but the joints and fasteners aren’t. In Seguin’s Hill Country flash-rain events, water finds the gaps and wicks to the sheathing behind. We map the wet spots with thermal imaging, pull the affected boards, let the cavity dry, then re-install with proper drainage gaps and taped seams.
- AFB evo in interior partitions settling at header gaps. The friction-fit design relies on exact stud-bay dimensions. When framers are off by even 3/8 inch, the batt settles over months and leaves a convection channel at the top plate. We find these with blower-door-directed infrared; the fix is removal, precise cutting, and reinstallation with compatible fire-rated sealant at the perimeter.
- Rockwool in unsealed attics performing below rated R-value. This isn’t a product defect, it’s an installation sequence error. We’ve audited attics in the Guadalupe Regional Medical Center area where Comfortbatt R-30 was laid over leaky top plates; the effective R-value dropped to R-19 equivalent due to wind washing. We pull the batts, seal every penetration with fire-stop caulk and rigid foam, then reinstall so the insulation actually does its job.
- Comfortbatt around can lights creating thermal bypass. Rockwool is rated to contact non-IC fixtures, but many Seguin electricians don’t know that and leave 3-inch gaps. The result is a chimney effect straight into the attic. We document the gap with photos, replace with proper Rockwool enclosures or fire-rated covers as code requires, and air-seal the fixture boot.
Our Rockwool Home Energy Audit Process
- 1
Schedule and scope. You call (830) 549-6646, a live person answers, and we book a 2-hour window. We ask square footage, age of home, and which Rockwool product you have - Comfortbatt, Comfortboard, or AFB evo.
- 2
Blower-door baseline. We run a pressurization test - a diagnostic that pulls air through your building envelope and measures leakage in CFM50. Most Seguin homes built 1985-2010 test between 3,500 and 5,500 CFM50 before any work.
- 3
Thermal imaging under pressure. With the blower door running, we scan walls and ceilings with infrared to find where conditioned air is bypassing the Rockwool. The pressure differential makes leaks visible that a static camera misses.
- 4
Insulation inspection and documentation. We access attic and crawl space, photograph installation quality, measure actual versus labeled R-value, and check for compression, gaps, or moisture staining. The photo record goes in your file.
- 5
Written findings and price. You get a printed report with blower-door number, thermal images, photo documentation, and a flat price for any corrections. No work starts until you have the written scope and price in hand.
- 6
Post-work verification. If we do the air sealing or reinstallation, we run the blower door again and hand you the before-and-after numbers. The report goes home with you - the numbers do the talking.

These are real Seguin numbers for homes we’re in regularly - from the older frame houses near Walnut Branch to newer builds toward McQueeney.

Why Seguin Homeowners Call Topside Attic Insulation Seguin for Rockwool Work
We’ve been independently owned and operated under The Haven Standard since 2016. That means a written price before any work starts, a Documented Photo Record on every visit, and before-and-after blower-door numbers when we do air sealing. Our technicians are background-checked and uniformed; calls are answered by a live person 24/7. We work with Rockwool, Owens Corning, Johns Manville, Knauf, and others - no proprietary lock-in, so we recommend what actually fits your home. We also service Reflectix radiant barrier systems, which matters in Seguin because many homes have hybrid insulation stacks that need someone who knows how the layers interact. The 365-Day Done Right Promise applies to everything we touch.
FAQs
No. Rockwool’s limited warranty covers manufacturing defects in the product itself, not installation or building-envelope performance. As an independent Rockwool service provider, we don’t alter your product warranty; we document whether the insulation is performing to its rated spec in your actual wall or attic. If we find a true material defect, we flag it for your Rockwool claim. Call (830) 549-6646 and we’ll walk you through what’s covered versus what isn’t.
We typically schedule within 48 hours, and most audits are completed in a single 2- to 3-hour visit. Emergency scheduling is available if you’re in a real estate transaction or dealing with an insurance claim. Call (830) 549-6646 to check next availability - a live person answers.
Repair the leaks first, almost always. Rockwool batts and boards are durable; unless they’re water-damaged or fire-compromised, the product is usually fine. The problem is the air moving around it. We seal first, test again, and only recommend removal if the blower-door numbers don’t drop enough or if the insulation itself is degraded. You’ll see the numbers and decide.
We don’t stock full Rockwool batts - those are project-ordered by dimension - but we carry the compatible sealants, fasteners, and fire-rated accessories for repairs and corrections. For full replacement, we source through normal distribution channels with no markup games. If another contractor quoted you Rockwool work, bring us the written estimate; we’ll give you a free second opinion.
A printed report with your blower-door reading in CFM50, annotated thermal images showing leak locations, photos of the insulation condition, and a written scope with flat price for any recommended work. If we perform corrections, you also get the post-work blower-door number and a second set of photos. Everything is dated and signed; it’s your record for resale, insurance, or warranty claims.
